Well, the question is how much lead will these new cars end up carrying to make weight? If they need more than just a nominal amount of lead, then yes, the cars COULD be made lighter. One of the safety advantages of a lighter car is that an object in motion tries to stay in motion, and the heavier that object is, the more it wants to keep bouncing off stuff. A lighter car would transfer less inertial energy to the driver.It's just a guess, but I think Ryan Newman would say it's worth it to lug around a few extra kilos...
The Gen 7 car has to thrive on high-banked ovals from Talladega to Bristol... which creates forces through the suspension and chassis that roadracing Supercars just don't see. Also, it's designed to take a hit like Newman took at Daytona, which Supercars also don't see and are not designed to survive.
I'm sure it would be possible to build the Gen 7 car lighter, including all the required strength and safety attributes for Nascar competition, but probably only at significantly higher cost. Weight reduction in race cars is invariably expensive.
